@andriybyelikov you can imagine the Interfere-Cards as a "counter spell" they just counter the effects of the card in the opposite slot (the effect be it hide / attack wont be put on the resolve stack), while still applying their send / receive effects.
There are some exceptions like cards with the encrypt modifier which can't be interfered as well as two interfere cards opposing each other, in this case the card with the highest priority applies first (the card setter always wins priority ties)
if something is unclear or you have any other questions fell free to ask them. ^^
